Thanks for the feedback and praise, all.
I did indeed write about the IWW, although mostly as background to the rise of the International Woodworkers of America - a more conventional CIO union, albeit one with a strong Communist influence in its early years. I wish I could link to my thesis here, but unfortunately the digital archive that hosts the online copy is only available to Reed students and alumni. I suppose I could stick it in a Google Drive if anyone's interested.
I don't think it's a spoiler to say that some of the factors behind syndicalism in the Northwest woods, especially the semi-nomadic camps that made traditional hierarchical organization difficult, will still be present ITTL.
I would love to read it!
